The surface area of a sphere with a radius of 13 units is 676π²
What is surface area?
explaination;
Given radius = 13 units
surface area of a sphere = 4πr²
= 4 * 13*13 π²
676π² answer.
- The surface area is the sum of the areas of all its faces.
- The areas of the base, top, and lateral surfaces i.e all sides of the object. It is measured using different area formulas and measured in square units and then adding all the areas.
- The surface area of a solid object is a measure of the total area that the surface of the object covers.
The floor region of a strong object is a measure of the full vicinity that the floor of the item occupies. The mathematical definition of surface vicinity within the presence of curved surfaces is extensively extra involved than the definition of arc length of 1-dimensional curves, or of the floor area for polyhedra for which the surface place is the sum of the areas of its faces. clean surfaces, such as a sphere, are assigned floor region using their representation as parametric surfaces. The definition of floor area is based totally on methods of infinitesimal calculus and includes partial derivatives and double integration.
